Might read through this post. It appears that the new ACR does not record the distance. Posts 1-3 describe the problem while latter in the thread there is a script offered as a solution. http://forums.adobe.com/message/5003474

Thanks Paul, I can see the distance within cs6, the problem is when a jpeg is saved, the distance is missing from the exif, when the same file is saved using cs5 the distance is saved in the exif & can be seen in my photos that are online, using my browsers exif viewer.

It is still there, but not where it used to be so what you could do copy it and put it back to it's original field. You could use ExifTool to extract and then put it back. Then you would be able to see it when online.

Another thing you could do is contact the people that host your pics and see if they are going to update their software.

Being the metadata seems to be in the Aux exif was the jpeg created by processing a RAW file and not saved using Save For Web or from the Camera. Camera may not record that info in the exif it writes for its most likely an optional field. The camera records that info in the makers metadata. Different versions of ACR may record different Adobe AUX EXIF metadata. Use Photoshop file info and check the advance tab and see if you can find it in there. I don't know if it will be there. You could try Posting an example jpeg file with all metadata included not a jpeg that was saved using save for web which by default strips most metadata like exif.

Here is two images, 1st image is edited with cs5, 2nd image with cs6, both using "save as" not save fer web, both exifs intact, the image edited with cs5 has the focus distance in the exif, & can be seen with my web browser & by right clicking in Windows Explorer > details, the image edited with cs6 doesn't have it.

I'm use FxIF viewer, an extension in firefox browser, & can see the focus distance in the image from cs5,, but not in the cs6 image, & as you can see the same with Properties > Details, it would be nice to get the same from the cs6 images.

I wrote in my first append I do not think that your Canon EOS 7D writes the distance in the EXIF metadata it creates in camera. That the distance is most likely in the Makers metadata. I think that the Adobe Raw Conversion writes some makers metadata into Image files metadata it writes. I know it does write to AUX EXIF metadata and I have seen it also add|put things like lens info or max fstop into EXIF data. Where Canon cameras do not. It look like it may be a difference in the versions of Adobe Raw converters. Try a jped from the camera not processed by LR or ACR. See what Canon writes.

Note the difference in the EXIF data in your two images I displayed these with CS5.

I still think you should process a JPEG from you Camera and see what EXIF data is shown in Windows Explorer and then in Photoshop. Also look at what info is in Windows Explorer for your Tiff or Jpeg out of DPP before Photoshop has a go at it I still think to has to do with RAW converted and Metadata and what done in the different version of Photoshop.
